Social Network Centrality, Social Construction Of Knowledge, And Nurse Practitioner Competency In Asynchronous Online Discussions Among Adult Gerontology Acute Care Nurse Practitioner Students, Sharon Schaaf

Organization, Information and Learning Sciences ETDs

The relationships between social network centrality, social construction of knowledge, and nurse practitioner competency among adult gerontology acute care nurse practitioner students participating in asynchronous online discussions were explored. Social network centralities (betweenness, in-degree, out-degree, closeness, and eigenvector) were determined through social network analysis. Social construction of knowledge was assessed by the Interaction Analysis Model (IAM). Nurse practitioner competency was evaluated using the Novice to Expert model. A retrospective exploration of an online discussion board from the College of Nursing at the University of New Mexico was conducted. The centralities of betweenness, closeness, and eigenvector demonstrated a significant relationship with …

Longitudinal Assessment Of Dementia Measures In Down Syndrome, Lisa Mason Koehl, Jordan P. Harp, Kathryn L. Van Pelt, Elizabeth Head, Frederick A. Schmitt

Neurology Faculty Publications

Introduction: Early detection of dementia symptoms is critical in Down syndrome (DS) but complicated by clinical assessment barriers. The current study aimed to characterize cognitive and behavioral impairment using longitudinal trajectories comparing several measures of cognitive and behavioral functioning.

Methods: Measures included global cognitive status (Severe Impairment Battery [SIB]), motor praxis (Brief Praxis Test [BPT]), and clinical dementia informant ratings (Dementia Questionnaire for People with Learning Disabilities [DLD]). One-year reliability was assessed using a two-way mixed effect, consistency, single measurement intraclass correlation among non-demented participants. Longitudinal assessment of SIB, BPT, and DLD was completed using linear mixed effect models.

Foster Inclusion By Focusing On Student Names, Brandy Bagar-Fraley

The International Institute for Innovative Instruction Blog

“To teach in a manner that respects and cares for the souls of our students,” writes bell hooks, “is essential if we are to provide the necessary conditions where learning can most deeply and intimately begin” (hooks, 1994, p. 13). An inclusive and equitable classroom is a manifestation of that respect and care. Instructors who deliberately cultivate an environment in which all students feel acknowledged and valued can reduce barriers to success and give all students the opportunity to flourish (Office of Planning, Evaluation, and Policy Development, 2016; Walton & Cohen, 2007). And there are many small, but significant, alterations …

Sex Workers And The Best Interests Of Their Children: Identifying Issues Faced By Sex Workers Involved In Custody And Access Legal Proceedings, Julie Eleanor Dewolf

LLM Theses

Sex worker parents often lose custody of their children. The purpose of this research was to determine what impact the status of a parent as a past or present sex worker has had on judicial decision-making in custody and access disputes. Through doctrinal legal research, I explored judicial treatment of sex worker parents in custody and access disputes in Ontario Child Protection and Family Law case law. Parental involvement in sex work was often presented as an unfavourable aspect of the parent, or otherwise had a negative influence on their claim. Sex work was treated as a negative quality in …

Gtpbp1 Resolves Paused Ribosomes To Maintain Neuronal Homeostasis., Markus Terrey, Scott I Adamson, Alana L Gibson, Tianda Deng, Ryuta Ishimura, Jeffrey Chuang, Susan L Ackerman

Faculty Research 2020

Ribosome-associated quality control pathways respond to defects in translational elongation to recycle arrested ribosomes and degrade aberrant polypeptides and mRNAs. Loss of a tRNA gene leads to ribosomal pausing that is resolved by the translational GTPase GTPBP2, and in its absence causes neuron death. Here, we show that loss of the homologous protein GTPBP1 during tRNA deficiency in the mouse brain also leads to codon-specific ribosome pausing and neurodegeneration, suggesting that these non-redundant GTPases function in the same pathway to mitigate ribosome pausing. As observed in

Ferric Uptake Regulator (Fur) Reversibly Binds A [2fe-2s] Cluster To Sense Intracellular Iron Homeostasis In Escherichia Coli, Chelsey R. Fontenot, Homyra Tasnim, Kathryn A. Valdes, Codrina V. Popescu, Huangen Ding

Faculty Publications

© 2020 Fontenot et al. The ferric uptake regulator (Fur) is a global transcription factor that regulates intracellular iron homeostasis in bacteria. The current hypothesis states that when the intracellular “free” iron concentration is elevated, Fur binds ferrous iron, and the iron-bound Fur represses the genes encoding for iron uptake systems and stimulates the genes encoding for iron storage proteins. However, the “iron-bound” Fur has never been isolated from any bacteria. Here we report that the Escherichia coli Fur has a bright red color when expressed in E. coli mutant cells containing an elevated intracellular free iron content because of …

2020-Current year OA Pubs

BACKGROUND: Although Schistosoma haematobium infection has been reported to be associated with alterations in immune function, in particular immune hyporesponsiveness, there have been only few studies that have used the approach of removing infection by drug treatment to establish this and to understand the underlying molecular mechanisms.

METHODS: Schistosoma haematobium-infected schoolchildren were studied before and after praziquantel treatment and compared with uninfected controls. Cellular responses were characterized by cytokine production and flow cytometry, and in a subset of children RNA sequencing (RNA-Seq) transcriptome profiling was performed.

RESULTS: Removal of S haematobium infection resulted in increased schistosome-specific cytokine responses that were …

Abundance And Diversity Of Dung Beetles (Coleoptera: Scarabaeoidea) As Affected By Grazing Management In The Nebraska Sandhills Ecosystem, Patrick M. Wagner, Gandura Omar Abagandura, Martha Mamo, Thomas Weissling, Ana Wingeyer, Jeffrey D. Bradshaw

Department of Entomology: Faculty Publications

Dung beetles (Coleoptera: Scarabaeoidea) serve a significant role in regulating ecosystem services on rangelands. However, the influence of grazing management on dung beetle communities remains largely unknown. The purpose of this study was to investigate dung beetle abundance and diversity throughout the grazing season in the Nebraska Sandhills Ecoregion. Grazing treatments included: continuous grazing (CONT), low-stocking rotational grazing (LSR), high-stocking rotational grazing (HSR), and no grazing (NG). The abundance and diversity of dung beetles were measured in the 2014 and 2015 grazing seasons using dung-baited pitfall traps. Dung beetle abundance for each grazing treatment was characterized through four indices: peak …

The Transition From Stochastic To Deterministic Bacterial Community Assembly During Permafrost Thaw Succession, Stacey J. Doherty, Robyn A. Barbato, A. Stuart Grandy, W. Kelley Thomas, Sylvain Monteux, Ellen Dorrepaal, Margareta Johansson, Jessica G. Ernakovich

Faculty Publications

The Northern high latitudes are warming twice as fast as the global average, and permafrost has become vulnerable to thaw. Changes to the environment during thaw leads to shifts in microbial communities and their associated functions, such as greenhouse gas emissions. Understanding the ecological processes that structure the identity and abundance (i.e., assembly) of pre- and post-thaw communities may improve predictions of the functional outcomes of permafrost thaw. We characterized microbial community assembly during permafrost thaw using in situ observations and a laboratory incubation of soils from the Storflaket Mire in Abisko, Sweden, where permafrost thaw has occurred over the …

Quantifying Structure And Variation In Complex Phylogenetic Data, Genevieve Geraldine Mount

LSU Doctoral Dissertations

Identifying the source and structure of variation in nature is crucial to understanding fundamental aspects of evolution. Despite a recent plethora of genetic and morphological data, many interesting questions about the relationships between different groups remain unresolved. My dissertation evaluates three approaches for identifying and quantifying the variation within phylogenetic datasets. Characterizing variation within datasets and across analytical methods gives insight into biologically interesting characters, unusual evolutionary processes, and areas for model improvement.

Network-based community detection approaches offer a powerful tool to describe variation in phylogenetic signal across the genome (i.e., gene tree variation). In Chapter 2, I investigate the …

Evolution Of Green Blood In New Guinea Lizards: Phylogenomics, Biogeography, And Comparative Genomics, Zachary Rodriguez

LSU Doctoral Dissertations

Non-model organisms with evolutionary novelties and complex distributions can provide valuable insight into the mechanisms underlying biological diversity. Green blood is one of the most unusual vertebrate physiologies and has repeatedly evolved in lizards from the megadiverse island of New Guinea. An unusually high concentration of the toxic green bile pigment biliverdin causes the green coloration of these lizards' blood, muscles, and bones. This dissertation uncovered the complex history of this novel trait (Chapter 2), identified protein-coding sequences that underlie green blood in lizards (Chapter 3), and explored evolutionary processes that drive genetic diversity in high-elevation lizards. To accurately trace …

Isolation Of Specific Phospholipids From Nannochloropsis Oculata Microalga For Cosmetic Applications, Ahmet Yener Manisali

USF Tampa Graduate Theses and Dissertations

Algae, photosynthetic aquatic organisms, have recently caught the attention of the food, cosmetic, pharmaceutical, and nutraceutical industries due to the variety of natural compounds in their cellular bodies such as carbohydrates, lipids, and proteins. Specifically, microalgae-derived natural compounds such as phospholipids are extensively utilized in cosmetics as part of liposome formers, emulsifiers, solubilizers, and wetting agents. Although phospholipids are currently extracted from food sources, this practice raises sustainability concerns. Hence, growing microalgae on the provision of macronutrients such as nitrates and phosphates will serve as a more sustainable source of the several specific phospholipids such as phosphatidylcholine (PC), phosphatidyl-ethanolamine (PE), …

Circadian Rhythms And The Embodiment Of Social Zeitgebers: Linking The Bio And Social, Tiffany R. Moore

USF Tampa Graduate Theses and Dissertations

Virtually all biological processes are under direct or indirect control of the circadian system. Chronic disruption of circadian rhythms, termed chronodisruption, is linked to increased risk for adverse health outcomes such as cancer, depression, and cardiometabolic disease. Circadian rhythms are highly sensitive to sociocultural contexts. As a result, circadian rhythms provide a valuable entryway to explore issues of embodiment. Here, embodiment refers to processes through which social experiences ‘get under the skin’ to become biological and manifest in health. To better understand what proximate social factors influence chronodisruption, this study assessed chronodisruption and social zeitgebers among a population of 15 …

Plio-Pleistocene Antarctic Ice-Ocean Interactions In The Ross Sea, Catherine Prunella

USF Tampa Graduate Theses and Dissertations

Warm, intermediate-depth Southern Ocean waters are implicated in recent Antarctic ice mass loss. Direct observations of Antarctic Ice Sheet (AIS) retreat are temporally limited, necessitating paleoceanographic records of ocean-ice interactions during past warm climate intervals. Deepsea and ice-proximal sediments record orbitally-paced glacial-interglacial fluctuations in AIS volume during the Plio-Pleistocene (last 5 million years; Ma), but the total contribution of the AIS and the role of ocean heat in these fluctuations remain unresolved. To address the response of Antarctica’s ice sheets to changing ocean temperatures during the Plio-Pleistocene, International Ocean Discovery Program (IODP) Expedition 374 recovered sediments from the Ross Sea …

Modeling Early Life: Ontogenetic Growth And Behavior Affect Population Connectivity In Gulf Of Mexico Marine Fish, Kelly Vasbinder

USF Tampa Graduate Theses and Dissertations

This dissertation is an examination of growth, behavior, and dispersal during the early life stages of marine fishes in the Gulf of Mexico. Understanding movements of early life stages is a key part of managing exploited fish populations. Position in the water column can impact larval dispersal, since it determines those currents to which larvae are exposed. First, I investigated the relationship between length and age in early life stages of marine fishes. I found that demersal fish taxa tend to be represented by exponential models, while pelagic fish tend to be represented by linear models. I suggest this may …
